Ironbound Warriors
From The Griffin's Crier
The Ironbound Warriors are a variant flesh golem that have been reinforced with bands of iron to better channel their innate rage. The golems were first created by the Hextorite clerics of the Steel Skull Mercenary Company. The secret was thought lost when Steel Skull Fortress was sacked by humanoids, but in CY 515 they resurfaced when Kor and his Wyvern Empire liberated the fortress.
